Hi, Just got my P40 and after some initial testing I was getting dissapointed it was benchmarking significantly below Surface Pro 4 i7 (Iris 540) in Cinebench and not that better in GFXbench. Granted the real benchmark is on my speciefic software needs but yet I was curious if I was doing something wrong.
Besides the known issue of the tablet driver to use too much CPU (which I fixed following a hint for Yoga 260), I also discovered that the Quadro QNF (new feature driver) was giving a significant boost in Cinebench (from 47 FPS, to 60 FPS OpwnGL).
so I write to see what is the catch? are there serious documented instances of instability of QNF drivers? any other issue I shoudl be worried about (e.g. heat management) of using the non ISV certified drivers?
-the QNF driver I installed is the 372.95; the latest driver from lenovo's support website I think is the 368.71; although I think somehow I got a 369.something from Lenovo companion auto-update.

I use QNF (And sometimes Beta) Drivers on my W530. Aside from the occasional glitch with the Beta line drivers, I haven't experienced issues with the QNF ones.

I've never actually run cinebench. I can once I get the OS sorted on my W530.
